As any smartphone aficionado knows, the accelerometer is one of the key sensors within the device – it allows the phone to know when and by how much it’s been moved. Accelerometers also have many ...

An optomechanical accelerometer that uses light to measure acceleration. Credit: F Zhou/NIST An accelerometer that uses laser light instead of just mechanical strain can register changes as small as ...

Setting the stage for a new class of motional sensors, researchers have developed a new ultrasensitive, microchip-scale accelerometer that uses laser light to measure displacement. Beyond consumer ...

Researchers at the California Institute of Technology (Caltech) and the University of Rochester have developed an ultrasensitive microsensor accelerometer. Their device uses laser light to gauge ...

Addressing the increasing demand to accurately measure acceleration in smaller navigation systems and other devices, researchers have developed an accelerometer a mere millimeter thick that uses laser ...

Illustration showing how a single laser beam is converted into four beams after diffracting from a patterned surface. These beams are then used to trap ultracold atoms in the new accelerometer.

The ability to measure, monitor, and analyze vibration is essential to many industries and areas of research & development. Unfortunately, the proper methods for creating an accurate and repeatable ...
